David Hasselhoff's divorce is set to turn nasty.It was revealed, the 'Knight Rider' star filed for divorce from actress Pamela Bach, after 16 years of marriage, earlier this week.Bach has now reportedly filed papers seeking custody of their two daughters and is seeking spousal and child support, despite Hasselhoff stating the couple had reached an "amicable settlement".It seems the star's estranged wife is determined to make the separation difficult and is not taking the break-up well.According to reports, Bach showed up at Courtney Fine's show 'Me2', an autobiographical work about her dating life, in West Hollywood last Thursday (12.01.06) and started screaming at the stage in a drunken stupor.Bach allegedly yelled: "I know a ***hole like that", and "I've been going through that **** for years!"Hasselhoff - who played heartthrob Mitch Buchannon in 'Baywatch' - and Bach - who appeared in numerous episodes of 'Baywatch' and 'Knight Rider' alongside her husband - cited irreconcilable differences for the split.
